- In the drawings, A A represent the series of paired rolls for feeding the round rat-an or other stock to the action successively thereon of the halving-saws B B to the saws B B arranged at right angles to the halving saws for centrally dividing both said halves, to the saws B B arranged at an angle of forty-five degrees to the quarteringsaws B and then to the fourth set of saws B, arranged in a plane atright angles to the ones B the saws B subdividing two of the quarters, producing the segmental eighths, while the last saws B similarly subdivide the other two quarters. Each pair of circular saws is mounted on the end of a shaft therefor, the teeth of the saws, as indicated in Figs. 11, 13, and 17, intermeshing or matching into the spaces between the teeth of its companion, although not quite touching the teeth of the companion saw, and both of the saws are positively driven to rotate in opposite directions by the meshing gearwheels 32 on the ends of the parallel saw-carrying shafts 30. The saws are clamped between collars 33 and secured by nuts 34, and. one of the saw-carrying shafts, which is geared to the other, as aforesaid, is driven by the pulley 35. The four sets of saws are mounted in journal bearings or heads 36 therefor, carried by standards or supports 37, all mounted on the parallel longitudinal bars 38 of the machine-frame and *have their intermeshing points all in the same common line of feed of the stock.

The pulleys for the respective saw-shafts are each driven by the respectively provided belt 39, all of which belts are driven from a common counter-shaft pulley or suitably otherwise.

The comparativelylong series of feed-rolls A A force and lead the ratan or other stock to the equalizing centering-guide D, arranged in relation to the first pair of halving-saws, so that the stock will be truly presented with its longitudinal median plane coincident with the cutting plane of the said saws.

Beyond the halving-saws and before the quartering-saws are reached is the guide D whereby the halves as produced by the first saws will each be guided so that the central radial line thereof will come coincident with the cutting plane of the quartering-saws B and between the first saws B and the guide D adjacent the quartering-saws B is a separating-guide a, the principal object of which is to insure that the forward ends of the halves of the stock will enter properly within the guiding spaces or passage therefor within the device D The separator-guide for the halves a is shown in Figs. 1, 2, 11, and 12, and the centering-guide for such halves is shown in Figs. 1, 13, 14, and 15, and next followihg the pair of quartering-saws B are separator-guides, (indicated and shown at a in Figs. 1, 13, and 16.)

The centering-guide D preceding the quartering-saws, and the separator-guide a following the quartering-saws, as indicated in Figs. 13, 14, and 15, are constructed in one fixture, although they need not necessarily be so constructed. This fixture comprises a tubular body 40, having in its end portion preceding the sawsthe widen'ed walls, as in'd'idicated-at 46. These are pressed inwardly by the spring 47. Between the members '45 45 is the vertical central partition 48, the plane of which is at right angles to that of the quartering-saws. This tubular fixtu re is intermediatelyslotted, as indicated at 50, from opposite sides to leave entrance-spaces for the interme'shing edge portions of 'the saws, the slots '50 from the opposite sides merging'into each other, and the said fixture has in its end portion in-the'lineof feed of the stock beyond the quartering-saws Eitscircular passage divided into quarter-spaces by'the radial and rightangularly intersecting partition-walls 52, as shown in Fig. "16.- a

Following the quartering-saws B in the line of feed is theguide D for the now produced quarters, carrying them to the third pair of saws B the same comprising centering appliances for the diametrically'opposit'e two of the quarters, the whole being constructed in the form of a tubular fixture following in colistruction and purpose similar ideas as embodied'in the device shown in Fig: 13; but m this device there are the quarter partitions,

making fourguiding chambers, as seen in Fig.

18, in two of which'are'centering-springs 47, so that the two quarter-segments will be truly presented radially in relation to the-third pair of saws, which cut those two quarters into eighths, and then following the saws B in the line of feed of the stock the tubular separating-guidea as'seen in Figs. 17 and 19, has

its passage partitioned by'the-walls 51 as a counterpart D or continuation' of the partitions seen in Fig. 18, the preceding guide with i the additional walls 51 ,wvhich separate the eighth segments as produced by the said saws B The guide D next preceding the last pair of saws B is partitioned by radial'walls and for the formation of separate longitudi -madly-extending passages corresponding to and as continu ations of separator-guides (seen in Fig. 19) which follow'the third set ol'saws, such separatorguides assuring that-those seg ments so far as producedand which have fur ther to'be subdivided when-brought through them will enter separate V-shaped guide-passages, respectively, therefor in thedevice D and this device is inmany respects similar to the one shown in Fig. 17. in longitudinal section, difiering therefrom in that the sawopenings and lateral pressure-springs-are arranged diametrically oppo'site, as will be perceived on viewing Fig. 21 in comparison with Fig; 18.

The centering or equalizing guide D for the whole ratan and the centering-guide D 'for insuring truly radially and centrally the pro-- sentation of the halves to the quartering-saws have or comprise opposite jaws, between. which the stock is passed, which jaws have which press inwardly boththe members 45 of the device 'D that is to say, 0n reference to Figs. 6, 7 ,a ndS, as follows: Upstanding from I the framing or stationary support forthe device D are the opposite ear-pieces 66 60, pi-v oted in which, at 61, are theinwardly-extend ingmembers 62 of the opposite jaws 63 63,

the upper endsof which have the iuwardly= facing-V-recesses 64'; 1 4

' Centrallybetween the jaws 63 63, playing through av'ertica-l guiding-socket 66 therefor, which is formed in a stationary-part or-fixtu re of the frame, is the shaft or stem 67, having pivoted to the upper end thereof at the points 69 69 the upwardly andoutwardly divergent links 70, which arealso pivoted at-72 to the jaws63. The spring-73 exerts a downward force on the stem by being constrainedfbetween the stationary part 7} and the nut or sh0ulder75 and serves to cause through the articulation of the parts of the device, as described, a closing pressure of the one jaw on the other. As the stock is introduced and-fed through and between said pressure-jaws of this equalizing-guide it is carriednor maintained with its center always in the same line, notwithstanding undulations orirregularitie's in its diameter, for the jaws must open-and will close toward each other always exactly equally.

As shown in Figs. 7 and 8, the shanks or lower portions of the opposite'jaws are apertured, as shown'at 76, to give'unobstructed space of occupancyfor the links 70, so that the device may be very compactin its organization.

Describing the constructionand manner of driving the 'feeding-rolls A 'A,'referen ce is now had to Figs. 9'and 10, the'latter'beinga rear view as taken from theside-opposite Fig. 1. All of. thelower rolls of theseries are mounted at the forward ends of the shaft 80, each having'ihercon the gear-wheel 82, one of these being driven from anotherby the idlers 8.3. The worm 84 on the pulley-driven shaft 85 drives the worm-wheel 86, which has on its elongated" huh'the spur gear-wheel 87, which meshes into two oi the separated'gearwheels 82 of the set. Each ot the upper feedrolls or feed-wheel s, which, it is understood, is essentially a pressure-roller and has. its rotary motion imparted thereto by'the stock as positively fed by the positively-driven lower rollers, has its journalrb'ar 90, bytherear end thereof, pivoted,.as seen at 92, inra lug or fixture 93 ofthet'rame of the'machineu Near the forward end of the shaft,'but behind the feed-wheels, arealso lugs ;or stationaryfixtures 9a, in which theelbow-levers '95 are at theirelbows pivoted, the short'arm of the lever. bearing with pressure dowhwardly against the bar 90, which pressure is imparted by the" spring 96', which 'by'its one &

end is hung to the long arm of the elbow-lever and with its other arm to the lug or part or fixture of the framing therefor. When the ratan is introduced between the feed-rollers, the upper one is separated against the pressure of the spring'as exerted through its force on the elbow-lever thereon. The rollers are formed with hollowed or peripherally-grooved rims and, furthermore, with serrations in the grooves to increase their certainty of feeding action; but such construction of the rolls involves in itself no invention.

It will be perceived on reference to Figs. 11 and 13 that as the stock is fed the teeth of the intermeshing saws as they successively approach the stock for the sawing action thereon work from the interior thereof outwardly towardthe opposite surfaces, and because of this mannerof sawing and because in practice the scale or glaze at the exterior becomes cleft or split on the sawing line slightly before the teeth of the saw actually reachthe exterior of the stock the saws are saved from the destructive action thereupon which would ensue in an operation where the saws cut entirely through the stock, as ordi narily practiced, wherein is necessitated the striking of the glaze directly by the saw-teeth Having thus described myinventiomwhat I claim, and desire to secure by Letters Patent, is
